It is expected that results from this study will provide increasing awareness and knowledge of the side effect profile of antidepressants on bone metabolism. This may prompt clinicians to screen patients at high risk of drug-induced osteopenia or osteoporosis and accordingly provide treatment, which may reduce the incidence of potentially avoidable fractures. Moreover, some types of antidepressants may show to produce a minimal or even no effect on bone turnover, and should be considered as first line treatment in the group of patients at risk of fractures.
